WICKHRAISER.

SPECIFICATION forming part of Letters Patent No. 372,639, dated November 1,1887.

Application filed April l5, 1SS7.

To all whom t may concern:

Be it known that I, FRANK RHIXD, ofilieriden, in the county of New Haven and State tubular character, andthe air to support combustion, or a portion of it, is led centrally up through the wick-tube, and such as commonly called Argand or Central-Draft lamps, and particularly to lamps of this classin which an inner or central tube 1reads up through the fount and forms the inner wall ot the wiekchamber, with a concentric tube outside this inner tube which forms the outer wall of the wick-chamber, the wick being adjustable up and down through the said chamber, and in which a collar is xed upon the outside ofthe lower end ofthe wick, and that collar having an arm extending from it into connection with a vertically-sliding rod outside the wicktube, and which extends up through the fount outside the chimney and so that by.,taking hold of the rod the wick may be raised orlowered; and the invention consists in the construction of the adjusting device, as hereinafter described,

` and particularly recited in the claim.

In the illustration, A represents the fount, which is oi' any desirable form, upon the top of which rests the shell of the burner B. Oentrally in the fountis the tube O. This tube extends up to the base of the llame in the usual manner for central-draft lamps, and is open at some point (here represented as through the bottom at D) forthe admission of air to the tube that it may pass upward to the burner. Outside the inner tube,O,and concentric with it, is a second tube, E, this tube being tixed to the burner and so as to be removed from the fount with the burner. This tube, when in place, has its upper end about in the saine plane with the inner tube, O, and the two tubes O E Serial No. 234,375. (No model.)

form, respectively, the inner andouter walls of the wick-chamber.

F represents the wick, which is of tubular form, and stands in the wick-chamber between the two tubes and extends down into the fouut to receive a supply of oil. Surrounding the inner tube, O, is a met-al sleeve,G,whieh closely lits the innentube, but so as to freely slide up and down thereon, the inner tube forming a guide for the movement of the sleeve G.

Parallel with the wick-tubes, but outside the burner, is a vertical rod, H, preferably tubular, for reasons hereinafter mentioned, and which extends up through an opening in the top of the fount and so as to be freely moved up and down therein, as indicated by broken lines. At itsy lower end the rod H is rigidly connected to the sleeve G by an arm, I, so that by moving the rod H up or down the sleeve G will be moved accordingly. 7o

To apply the wick. the burner is removed, taking with it the outer wall, E. Then the rod H is drawn upward, as indicated in broken lines, taking the upper end of the sleeve G out above tlie top of the fount. Then the tubu- 75 lar wick F is set on around and outside of the sleeve G, which the wick closely iits, and so close as to adhere firmly to it, that any vertical movement imparted to the sleeve will be correspondingly imparted to the tube.

Additional appliances may be employed,if necessary,to secure the wick tothe sleeve; but in any case the sleeve is practically the wickholder, and sliding on the inner tube alone controls the movement of the wick.

After the wick has been applied the rod H is forced downward,'taking with it the sleeve and wick to its required position. Then the burner is replaced,bringing the outer wall, E, to its place around the outside of the wick.

I make the vertically-sliding rod tubular for the purpose ofutilizing the rod as a filler-opening for the fount. Its upper end is closed by a screw-cap,L, similar to the illercaps usually applied toa lamp. 95

To tillthe fomit, remove the cap L and pour the oil through the tube H into the fount, the tube being openinto the fount at its lower end, so that the oil will freely ilow into the fonnt.

I do not in this application claim, broadly, Ioo

` of said sleeve G and held to move with the said I lsire to secure by Letters Patent, is-

an adjusting device outside the Wick-tube in sleeve, a sliding tubular rod, H, parallel with connection With the Wick-holder made' adj ustsaid tubes and extending through the fount able vertically, or made tubular, such tubular outside the burner and connected with the said 15 Wick-adjuster being shown in my Patent No. sleeve G inside the fount, the said tubular rod 361,545, dated April 19 1887; but H opening at its lower end into the fount and What I do claim in this application,and deprovided With aelosing-eap at its upper end, I substantially as described.

n a central-draft lam ,the combination of the central tube, C, the ouer tube, E, thesleeve FRANK RHIND' G, surrounding the inner tube and adjustable thereon, the Wiel; F, applied upon the outside Witnesses:
